Mechanical Characteisation of Rice Husk Flour Reinforced Vinylester Polymer Composite

Dr.Shivappa, Ananda.G.K, Shivakumar.N

The present research work is more dedicated in the development of more and more natural fiber composites as it serves the purpose of industrial and domestic requirements with the use of bio degradable products. Bio degradable products like coconut coir, jute, and rice husk are naturally available and are not harmful to the nature like synthetic fiber. In this study, composites were prepared with unmodified Rice Husk Flour (RHF) as a filler and Unsaturated Vinlyester Resin (UVR) as the matrix. 0%, 2.5%, 7.5% and 10% by weight of filler percentages were used in order to gain insights into the effect of filler content on the mechanical properties (Tensile and Flexural) of the composite produced using Hand Layup method. Three samples of different percentage fractions are tested and SEM analysis made on samples. With this study we come to know the compatibility of rice husk fiber with vinylester and contribution in the mechanical property of a matrix.
